Description

BACKGROUND

Technical Field

The embodiments herein generally relate to the field of textile dyeing and printing. The embodiments herein are particularly related to a system and method for dyeing colors on fabrics in an environmentally friendly manner. The embodiments herein are more particularly related to a system and method for dyeing fabrics on demand

Description of the Related Art

Dyeing fabrics is a well-known technique used for centuries. Dyeing is the application of dyes or pigments on textile materials such as fibers, yarns, and fabrics with the goal of achieving color with desired color fastness. Dyeing is normally done in a special solution containing dyes and particular chemical material. Dye molecules are fixed to the fiber by absorption, diffusion, or bonding with temperature and time being key controlling factors.
Typically, dyeing is done by “Yarn dyeing”, where the yarns are dyed first before the fabric manufacturing stage. Dyeing is also done by “Garment dyeing”, where the garments are constructed of undyed fabrics and then the whole garment is dyed by soaking in a color pigment.
Textile printing is the process of applying color to fabric in definite patterns or designs. In properly printed fabrics the color is bonded with the fiber, so as to resist washing and friction. Textile printing is different to dyeing, as in dyeing properly the whole fabric is uniformly covered with one color, whereas in printing one or more colors are applied to it in certain parts only, and in sharply defined patterns. The most common method of printing is “Direct printing” or “Textile Printing”, in which colorants containing dyes, thickeners, and the mordants or substances necessary for fixing the color on the cloth are printed in the desired pattern.
Dyeing and printing are different applications; in printing, color is applied to a localized area with desired patterns. In dyeing, it is applied to the entire textile. The quality of fabric from printing is generally not considered to be at the same level as dyed.
The quality of fabric from printing is generally considered to be of lower quality than dyed fabrics. All premium apparel and accessory are made from dyed fabric and not from printed fabric. For example, if a printed fabric is stretched, the original fabric color (typically white) will show through. For this reason, a printed suit, for example, can never be made to the same quality standards of a suit made from dyed fabric.
It is a well-known fact that the fashion sector was responsible for 2.1 billion metric tons of greenhouse-gas (GHG) emissions in 2018, about 4 percent of the global total—that's more than France, Germany and the UK combined that year—making it the second largest polluter in the world. The fashion industry is also the second largest consumer of the world's water supply, accounting for 20 percent of industrial water pollution globally and 79 billion cubic meters of water in 2017 alone. Using processes and machines that waste less water and materials is an obvious way for the fashion industry to significantly reduce its impact on the environment.
Unlike a digital printer, the dye-print machine, described herein, uses a pre-mixer to create a composite color, which is then deposited on to a substrate. The dye-print machine can only use a single color at any given time. So, it cannot print a photo or multi-color pattern like a digital printer. Typical quality of print in digital printing is defined by dots per inch (dpi), the number of dots the printer can print in a given inch.
In a traditional digital printer, fluid surface tension naturally pulls a stream into droplets. Optimal drop sizes of 0.004 inch require an inkjet nozzle size of about 0.003 inches. Fluids with surface tension may be water based, wax or oil based and even melted metal alloys. Most drops can be electrically charged. There are two main technologies in use in contemporary inkjet printers: continuous (CIJ) and drop-on-demand (DOD). Continuous inkjet means the flow is pressurized and in a continuous stream. Drop-on-demand means the fluid is expelled from the jet nozzle one drop at a time.
In a typical digital printer, there is no mixing of colors. It involves printing lots of tiny single-color dots, one next to the other, the quality of print being determined by the dpi (dots per inch). In a typical direct-to-garment or textile printing, colors are never mixed, rather it prints millions of dots of cyan, magenta, yellow or black color in a predetermined size and frequency: it is our eyes and brains that process this information to reproduce color! It is important to note that a digital printer deposits one of C or M or Y or K as the print dots. It is our eyes that create the illusion of color.
One of the key drawbacks of digital printing, especially for fabric printing is called “grin”. This is the tendency of a printed fabric to show the underlying color (typically, white) when it is stretched.
Hence there is a need for a system and method for dyeing fabrics on-demand. Further there is a need for a special type of printer device that is able to dye-print only one color at any given time (unlike a typical digital printer which prints millions of colors as tiny dots). Still further there is a need for a special type of printer device that is able to deposit a dye on both sides of the substrate, with two synchronized nozzles and to stretch the substrate during dye-print. Yet further there is a need for a dye print device that mixes the CMYK colors in the right proportion, just before it reaches the nozzle/head for printing, in real-time.

FIG. 3 illustrates schematic representation of inks being pre-mixed to create a composite color, which is then deposited on to a substrate, according to an embodiment herein.
According to an embodiment herein, two print heads are used to dye the fabric. One head/nozzle is operated/moved on top side of the substrate while another head/nozzle is operated/moved on the bottom side of the substrate, thereby enabling both the heads to dye the same color synchronously. According to an embodiment herein, both the heads are used/operated/moved asynchronously. A micro controller device is provided to calibrate the dye for the two heads/nozzles by calculating a linear distance between the two and a time taken for the fabric roll to travel the distance between the two.
According to an embodiment herein, the composite color is dynamically mixed as a process color from ink containers, that at least includes C, M, Y, K (Cyan, Magenta, Yellow & Black). The inks for C, M, Y, K (Cyan, Magenta, Yellow and Black) are mixed before being deposited through the nozzle. According to an embodiment herein, the color mixer is an analog device and a tap is used to control the flow of ink. When the color mixer is configured once, then the color mixer is configured to mix only that color till the color mixer is re-configured manually.
According to an embodiment herein, a dye print device needs to be instructed to switch/change color using a “reset” mechanism. According to an embodiment herein, the reset mechanism is configured to instruct the color mixer to mix a different set of CMYK, then instruct the nozzle to dye the substrate till the old color is fully used up, dyeing a swatch with the new color till saturation is reached and then start the new dye job.
According to an embodiment herein, water-based dyes are easily used which are less toxic and more environmentally friendly. The device itself is manufactured/built economically because the device uses only one color at a time.
According to an embodiment herein, the system comprises a flat bed for laying the fabric, a roller mechanism for the undyed fabric roll to be loaded, a moving head assembly for the nozzle to move in at least one direction through the entire length of the flatbed, an ink feeder mechanism, nozzle and an operator console. Using the operator console, the color for dyeing is chosen. According to an embodiment herein, a shape to be dyed is input as well. The shape includes but not limited to rectangle, sleeve shape, etc. A computing device is attached to the console to control the nozzle to turn it on/off and the moving head assembly to move and dye the fabric. The roller rotates the fabric roll in a smooth motion so as to enable the nozzle to dye different parts of the fabric.
